Understanding Modern Development Frameworks: A Guide for Developers and Technical Decision-makers
Understanding Modern Development Frameworks: A Guide for Developers and Technical Decision-makers 관련
As a developer for over 20 years, I've seen firsthand how choosing the right framework can make or break a project. The term "framework" has become so broad that it's often misunderstood. Let's clear up the confusion and help you make better technical decisions.
What is a Framework?
In terms of software development, a framework is a structured set of tools, libraries, and conventions that provides a foundation for building applications more efficiently by handling common functionalities so developers can focus on unique features.
A modern web application can combine multiple frameworks to handle different aspects of development efficiently:
- React with Tailwind CSS manages the user interface and styling.
- FastAPI or Django with LangChain handle backend operations and AI functionality, while MongoDB acts as a memory store.
These frameworks communicate through APIs and defined interfaces to work together—for example, a user interaction in the React front end can trigger an AI process through LangChain in the Python back end, which uses MongoDB Atlas Vector Search to retrieve relevant data and then display it back to the user with Tailwind CSS styles.
The Framework Landscape in 2024
Think of frameworks as tools in a technical toolbox. Understanding what each tool is designed to do—and what it isn't—ensures you use the right solution for the task at hand.
